Design for testing device used to measure air leakage from linear pneumatic actuator
Kurillová, Katarína ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This thesis is focused on detecting air leakage in serial production of pneumatic linear actuators. Testing for air leakage is an important part of the production process in which the manufacturer ensures that the product satisfies quality requirements and works correctly. The thesis was created in collaboration with the Czech manufacturing plant of SMC Industrial Automation CZ s.r.o., which produces pneumatic actuators. Goal of the design part of the thesis is to select the most effective method for testing and finding universal principle for testing in specified conditions. The principle is then applied to design a testing device for the CQ2 cylinders. The testing device consists of three parts - pneumatic circuit, control circuit and electric circuit. Thesis conclusion contains comparison of the newly designed testing device with the device currently in use.
Systémy pro měření průtoku dojeného mléka
ZAJÍC, Zdeněk
The thesis deals with systems for measuring the flow of milked milk. At the beginning of the work the history of cattle breeding in the Czech Republic is described as well as the process of milking, the issue and the principles of a flow measurement. The second part deals with certification from the association ICAR and with selected flowmeters, too. The main chapter includes the principles of selected flowmeters´ operation. The selected flowmeters of milked milk, which have been certified by ICAR, are described and compared here.
Monitoring of the sewerage system in the city of Brno
Dvorský, Petr ; Prax,, Petr (referee) ; Hluštík, Petr (advisor)
This thesis deals with the monitoring of the sewerage system in the city of Brno. In the research part, there is made an overview of the most used measuring equipment for the monitoring of the sewerage system – level meters, flowmeters, automatic samplers. The practical part is devoted to the monitoring of the sewerage system in Brno for partial evaluation of the benefits of the project „Reconstruction and completion of sewerage in Brno“, realized in 2012 – 2014. Measuring campaign has taken place from June to October 2017. In the course of the work, the instalation of measuring equipment and the collection of measured data was done. After finishing measuring campaign, the data were evaluated from different aspects – the number of overflows, the quantity of overflowing water, the dilution ratio and the quantity of discharged pollution. Then, the hydraulic and construction technical assement of the pipelines of sewer network and overflow chambers and assements of the quantity of the rainwater were made. The results of the evaluation were compared with the results of the previous monitoring campaingns and with the data obtained before the project has been realized. Based on this, the benefit of the project was determined.
Flow measurement
Schoř, Zdeněk ; Boček, Petr (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with flow measurement of liquids. The first part is a theoretical analysis with an overview of the most important parameters of flow sensors, the main parasitic influences and methods for calibration of flow sensors. The second part is the design and realization of the laboratory apparatus for measuring the flow of water, which is intended for the teaching of students. The apparatus is designed to test four flow sensors using weighing reference. The result of the practical part is the measurement of the basic characteristics of the flow sensors used and comparison of the obtained values with the data from a manufacturer. Further parasitic influences are added during the measurement and is determined to what extent they affect accuracy of the measurement.
Evaluation of the method using portable measuring system with flow-meter
Štarhová, Marie ; Šafář,, Robert (referee) ; Žoužela, Michal (advisor)
This diploma thesis deals with the assessment of flow measurement method using portable measuring set with the flowmeter used in the field of official measurement in the free surface profiles. This method is a controlled simulation of the required flow through a portable measurement set. This approach is innovative in relation to other methods of official measurement in which direct flow measurement is carried out. The thesis is based on extensive literary research related to elementary element of this assembly – flowmeter. On the basis of individual characteristics, the technical and metrological requirements for both the flowmeter and the other elements of the measuring set are processed. In the context of these findings and the requirements of the official measurement, input sources of measurement uncertainties are further defined and subsequently calculated by this assembly. The findings from this thesis are fully applicable to the practice of institution authorized for the official measurement of the subject method.
Electromagnetic current meters of velocity
Březina, Jiří ; Zubík, Pavel (referee) ; Žoužela, Michal (advisor)
This bachelor thesis explains the issue of electromagnetic current meter of velocity. A survey of all available standards on these devices is carried out. Devices are described technically and metrologically. There are also described the possibilities of usage, operating conditions as well as problems of calibration of these devices. Information on available commercially available devices is provided along with a description of all relevant parameters. One selected device model is put to the test of measurement the velocity on the calibration tank of the laboratory, thus the experiences from real calibration measurement are gained and described.
Flow rate measurement for hydraulic turbine model tests
Neděla, Jiří ; Dokoupil, Pavel (referee) ; Machů, Tomáš (advisor)
This thesis deals with problematice of flow rate measurement for hydraulic turbine model tests. Theoretical part is devoted to literary search of flowmeters and comparison of their accuracy. The practical part deals with evaluation of measurement uncertainties during calibration of the flowmeter. It also includes verification of the measurement accuracy of the flowmeter indicated by the manufacturer.
Model of cleaning station for food processing technology controlled by a control system na PROFIBUS network.
Vyskočil, Jaromír ; Sobotka, Milan (referee) ; Pásek, Jan (advisor)
This bachelor’s thesis deals with design, realization and laboratory commissioning of the model of keg / tank cleaning station (CIP) in foodstuff industry. The model uses two cleaning liquids – water and lye. There are several different types of valves used in the CIP model. They serves for inlet and outlet of lye or water and for separation of the both liquids branches. The control system offers monitoring of pressure, volume flow, level of the lye, etc. The measuring devises mostly communicate with PLC via industrial net PROFIBUS-DP and PA. The same net PROFIBUS-DP also provides communication between PLC and distributed control system Festo (valve island). Configuration and set up of the Festo valve island is described in the thesis as well. Further the work presents processing of the analogue values from different transmitters and their representation in a operator panel. Operator panel (OP) serves for control and visualization of the cleaning station. The OP configuration, the screens structure and the full functionality in the CIP station is explained. The individual screen description is incorporated as well. There are three modes of control – manual, semiautomatic and automatic. Automatic control is based on the recipe concept and the cleaning philosophy is split into several phases. The PLC control is presented in the form of flow diagrams algorithms and the program code in STEP7 is enclosed in attachment on CD ROM.
